Maybe you want to transcode and skip Flash altogether.
Please explain.
Convert your FLV (or, for much better quality, the original file
format that was compressed into FLV) into H264 MPEG 4 and OGG.V
formats, and serve them within a <video> container element in an HTML5
page. There are hundreds of examples how to code that on line, and I
think I saw one earlier today in this list on another topic.
Flash seems to be the best compromise between compression and clarity.
I am open to other formats.
You'll get a wider playback audience (including iDevices) and the
visitors will get dramatically better battery life/processor
performance in the bargain.
Why would that be?
iDevices don't show Flash at all, and probably won't ever. So no
amount of FLV will give you those tens of millions of eyeballs for
your movies. Sites as general purpose as YouTube have realized this
and serve up H264 for them, Flash for those who don't understand the
standards.
Flash in general causes a dramatic spike in processor usage (to decode
the format), which translates into battery drain on portable devices.
It's a really serious amount of difference, adding up to 1 or more
HOURS more play time on a laptop when viewing HTML5 <video> vs. Flash.
On phones, the difference can be even more striking, like cutting your
battery life nearly in half, due to the complete lack of hardware
acceleration for FLV decoding there.
